This was a mildly interesting science-fiction story. It seems that there is a problem on an asteroid, Y-3, where there is a base employed to check incoming spacecraft for germs, viruses and such noxious things. Well, the people on the asteroid have begun to stop working. They just spend their days lying out in the sun. They claim to have become plants. The Pipers in the woods have trained them to become plants. They can now do nothing else. Dr. Henry Harris is dispatched to investigate. It was a fun enough story and not overly long.
